The only church to attain the status of a basilica in Karnataka, St. Mary's Basilica first came up as a small chapel in 1818 courtesy French missionary Abbe Dubois. In 1882 Reverend Kleiner transformed this humble structure into a magnificent Gothic style church by adorning it with decorative stained glass imported from Europe. The St Mary's Church was conferred the status of a Basilica in 1973 through a papal order by Pope John Paul IV.
The St. Mary's Basilica church boasts of an elegant interior with
stained-glass windows, multiple columns with rich Corinthian capital
supporting stately arches. In September each year, lakhs of devotees,
dressed in saffron, gather here to celebrate St Mary's Feast.
